I was driving home last night from working experiencing my tachometer jumping all over the place. Im thinking this would be a misfire so I went home and swapped out power transisters/coilpacks.

That didnt work so I plugged the old ones back in and now this is where the horror begins.

The car BARELY starts and when it does, I have to give it a little gas, but even then it sounds like its running HORRIBLY.

I checked all my plugs and they seem to be in good shape, bpr6es ngk with new ngk wires just replaced so it cant be that.. could it?

Almost like its firing off 1 piston only..

So I thought to myself "Hey, why not check the ECU cause you've been putting that off since forever."

So I did.

Heres what came about.

^^non eprom

^^whats all that stuff for?

^^minor acid damage and a crappy caps replacement job

UPDATE: Swapped out spark plugs to avail. But I figured out that cylinders 2 and 3 are getting no spark at all.

Could it be the power transistor? I have 2 others to change out but they all do the same thing... @_@ Im puzzled here guys ;(
